I am 40 (as of tomorrow May 1 anyway) and live in Tampa FL. My primary source of exercise is inline skating, which I just got into back in late January and have already purchased 2 pairs of new skates. A lot of my skating group also bike, and have me interested in joining them at the park we skate/bike at. It's a nice 7 mile loop, flat, smooth paved trail in a "wilderness" environment.
I am currently in the market to find a road bike that is at least good enough to allow me to keep up. I borrowed a nice bike once and we did 21 miles, keeping a 16-22mph pace (primarily 19-20). We have a couple skaters that join a couple bikers in this and the bikes do the work of leading them around (yes, we have skaters in our group that can keep that pace for 21 miles).
I have a thread started asking a question about a couple bikes, any input would be helpful.
